Sori

Kim So-ri (, born July 21, 1990), professionally known by the mononym Sori, is a South Korean singer and actress.

She is a former member of the duo CocoSori and the project girl group Real Girls Project.

Kim So-ri was born on July 21, 1990, in Mapo District, Seoul, South Korea.

As a teenager, she migrated to Japan for her secondary education.

Additionally, she became a cheerleader at her high school, which became the "base experience that made her yearn for the stage."

Following three years in college, Kim returned to South Korea to pursue a career as a singer, where she signed with the South Korean entertainment company Mol Entertainment in 2013, subsequently appearing in the music video of "B.I.K.I.N.I" by Kim So-ri alongside Nine Muses member Sojin on August 15, 2013.

She debuted as an actress the following year in KBS2's romantic comedy television series Hi! School: Love On, in which she portrayed a high school student.

Following three years of training, Kim debuted under the mononym Sori as one-half of the duo CocoSori with the single "Dark Circle" on January 4, 2016.

The duo's image was compared to the girl group Crayon Pop due to their similar musical direction and unconventional music videos.

CocoSori auditioned to become members of the project girl group Real Girls Project on May 6, 2016, resulting in Sori scoring a spot in the group.

The group debuted with the single "Dream" on August 24, 2016.

Consequently, she was billed as one of the main cast members of Amazon Video's musical drama television series The Idolmaster KR, a South Korean adaption of the video game series of the same name.

The series premiered on April 28, 2017, and ran for twenty-four episodes prior to its conclusion on October 6, 2017.

Alongside former Real Girls Project groupmates Heo Young-joo, Lee Ye-eun, and Yukika Teramoto, Sori competed as one of Mol Entertainment's four representatives in JTBC's reality television competition Mix Nine, during which she became the subject of controversy following a comment made by the judge Yang Hyun-suk regarding her age and the state of her career.

She released a single titled "To Myself" in the midst of the controversy on November 5, 2017.

Sori ultimately finished in seventh place in a field of ninety-seven female contestants and therefore became a member of the resulting girl group during the final episode on January 26, 2018.

However, the group was defeated by their male counterpart for the opportunity to debut after the former garnered 7,866 points against the latter's 8,114 points.

Sori announced her debut as a solo artist through her official YouTube channel on July 31, 2018.

She launched a Makestar project in order to fund the expenses of her debut on August 1, 2018.

The project ultimately concluded on August 28, 2018, with over $20,000 raised by approximately 250 supporters.

Sori's debut single titled "Touch", featuring the rapper Basick, was released on September 4, 2018, in conjunction with the premiere of its music video.

The song was arranged, composed, and penned by the record producer Gamen Rider.

The music video was directed by the film director Hong Won-gi of the video production company Zanybros.

"Touch" was performed for the first time during its showcase held at the Dongja Art Hall in Seoul, South Korea on the day of its release.

The single enjoyed minor commercial success, where its physical version debuted and peaked at number 49 on the Gaon Album Chart.

To promote the single, Sori performed on music programs and radio programs, and held street performances as well.

A Japanese version of "Touch" was released as her debut single in Japan on November 14, 2018, with the music video premiering two days later.

The Japanese version was performed for the first time during its showcase, which was held for four days at the HMV flagship in Harajuku, Shibuya.

Sori launched a Kickstarter project on December 7, 2018, in order to fund the expenses of her sophomore release.

Throughout its run, she documented herself preparing the rewards for the supporters of the project on her YouTube channel.

The project concluded on December 21, 2018, with over ¥3,000,000 raised by around 260 supporters.

The music video for the song titled "I'm Ready", featuring the rapper Jaehyun, subsequently premiered ahead of its release.

It was directed by the film director Kyotaro Hayashi.

The single was ultimately released on December 26, 2018, through several music portals.

"I'm Ready" was composed and penned by Gamen Rider, who previously worked on "Touch".

Promotions for the single were held the following month due to the holiday season, which included a collaborative performance with the internet personality StarTy in Hongdae, Seoul.

"I'm Ready" was re-released on February 8, 2019, in Japan prior to Sori's first fanmeet titled '' SoriNation in Japan", which was held on February 11, 2019, at Club Citta in Kawasaki, Kanagawa. The fanmeet was presented by the singer Miho Miyazaki, while choreographers MikuNana and former Real Girls Project groupmate Lee Su-ji appeared as guests. The single debuted and peaked at number 126 on the Oricon Singles Chart.

Following CocoSori's disbandment on March 6, 2019, Sori became the host of a segment titled Sori Action for TBS' variety show Fact in Star.

Its first episode premiered on March 13, 2019, in which she analysed the music video of "Noir" by the singer Sunmi.

Sori subsequently became a cast member of Channel J's travel documentary Travel in Japan That Even Japanese Don't Know for its fourth and fifth season set in the Ibaraki Prefecture and the Tottori Prefecture respectively.
